When I write a text and I want to link a file or another text on Workspace, I need to copy the url of the document I want to link to first, then edit the link (so it is /#page-32-blablabla, not https://workspace.mydomain.private/#page-32-blablabla) and then go to the text I currently write, select text, click the link button and paste the link into the page.

I am used to being able to browse the contents of my server when I want to link to something, much like e.g. the Mindtouch wiki does.
